Monitoring e-business Web services usage through a log based architecture

The emergence of Web services represents a significant advance in the continuing evolution of e-business. In order to fully explore business opportunities provided by this paradigm, it is important to track its utilization. This can be done through the use of logging facilities. However, current Web logging approaches do not contemplate Web services utilization. This paper presents a Web services logging architecture based on SOAP intermediaries that captures comprehensive services usage information, which can be explored to improve B2B and B2C transactions by providing feedback on customer electronic behavior.

GARSA: genomic analysis resources for sequence annotation

SUMMARY Growth of genome data and analysis possibilities have brought new levels of difficulty for scientists to understand, integrate and deal with all this ever-increasing information. In this scenario, GARSA has been conceived aiming to facilitate the tasks of integrating, analyzing and presenting genomic information from several bioinformatics tools and genomic databases, in a flexible way. GARSA is a user-friendly web-based system designed to analyze genomic data in the context of a pipeline. EST and GGS data can be analyzed using the system since it accepts (1) chromatograms, (2) download of sequences from GenBank, (3) Fasta files stored locally or (4) a combination of all three. Quality evaluation of chromatograms, vector removing and clusterization are easily performed as part of the pipeline. A number of local and customizable Blast and CDD analyses can be performed as well as Interpro, complemented with phylogeny analyses. GARSA is being used for the analyses of Trypanosoma vivax (GSS and EST), Trypanosoma rangeli (GSS, EST and ORESTES), Bothrops jararaca (EST), Piaractus mesopotamicus (EST) and Lutzomyia longipalpis (EST). AVAILABILITY The GARSA system is freely available under GPL license (http://www.biowebdb.org/garsa/). For download requests visit http://www.biowebdb.org/garsa/ or contact Dr Alberto Dávila.

Estudo comparativo de softwares de construção de tesauros

Para auxiliar a construcao de vocabularios o uso e, consequentemente, a escolha de um software de construcao de tesauros e uma necessidade. Entretanto, esses softwares possuem diferentes caracteristicas de funcionalidades, custo e apoio metodologico, cuja analise criteriosa deve ser considerada, visando orientar a sua escolha de acordo com a finalidade e complexidade do tesauro a ser construido. Com base nessa necessidade de avaliacao, o objetivo do presente trabalho e apresentar um estudo comparativo desses softwares, levando em consideracao as utilizacoes dos tesauros nos dias de hoje.
